surface finish 3D printing surface treatment

Summary:       Different surface treatments can be used for different materials. Here is a description of the various surface treatments for different materials.

For most resin materials:


Spray painting

Spray painting is one of the main coloring processes for 3D printed products. It is the application of specific pigments to the surface of 3D printed products by spraying to form a thin film. Spray painting can improve the appearance of the product, making its surface smooth and even, and can add rich colors and patterns to the product to meet design needs. Spray painting also improves the durability and oxidation resistance of the product, extending its service life, and is second only to electroplating in terms of gloss. 

There are many colors you can choose for spray painting. If you don't find what you want in the standard colors, you can click on “Query pantone color number” to choose the name of your favorite color number and fill in the color column.

Electroplating

Electroplating is an electrochemical process that deposits a thin layer of metal ions on the surface of a part. The plated surface greatly enhances the strength of the underlying part and improves the material's resistance to abrasion, UV light and corrosion. Metallization effects can be achieved on non-metallic 3D printed products, providing more options. At the same time, the plating layer can also improve the electrical conductivity of the product, which is suitable for a number of applications that require electronic connectivity or conductive functionality.

There are many colors you can choose for electroplating too. If you don't find what you want in the standard colors, you can click on “Query pantone color number” to choose the name of your favorite color number and fill in the color column.

Sanding

Sanding is the removal of layers, bumps and imperfections on the surface of the print by mechanical or chemical means to make the surface smoother and more uniform, enhancing the overall texture and visual effect of the product. Sanding can also repair flaws and defects created during the printing process, improving the precision and quality of the product.

It can improve the surface quality of the product without changing its shape and structure, and is suitable for a variety of 3D printing materials and products with complex structures.


For nylon materials


Spray painting

The spray painting also can be used on the nylon prints. 

 

Dying

Dyeing is usually applied to more absorbent materials, like nylon which is absorbent is suitable for this method. Dyes change color by adsorbing or penetrating the surface of the print. The dye reacts chemically with the material on the surface of the print piece to form a stable color. However, the dyeing process may be uneven, resulting in color differences or mottling on the surface of the product, which affects the overall aesthetics of the product.

There are many colors you can choose for dying too. If you don't find what you want in the standard colors, you can click on “Query pantone color number” to choose the name \of your favorite color number and fill in the color column.

But the dying not applicable to HP-PA-12 nylon.
